Mic'ing principles are the same for just about any application: Find the sound you like first, then find the "sweet spot" and put the mic in the sweet spot, and record it. If you like what you hear in the room, you should like what you hear in the recording.

Going direct (DI) without an amp is similar in that you need to find the sound you like, then record it.

At first, I highly recommend using the "studio" as transparently as possible.
